Methods: This multi-center survey was conducted from December 2015 to March 2016. A multi-stage stratified random sampling method was used to sample representative diabetes physicians and patients in 18 hospitals in Shaanxi province, China. A self-designed questionnaire was used. The questionnaire mainly consisted of 2 questions for physicians and 1 question for patients of which the participants were required to rank in priority of 3 (for physicians) and 2 (for patients) choices from a list of barriers. The strategies to improve diabetes control were only in the questionnaire for physicians. Results: A total of 85 physicians and 584 patients completed the questionnaire. Physicians and patients differed regarding the patients’ awareness of the risk of diabetes: over 70% of the physicians believed that the patients had no sufficient understanding of the harm and risk of diabetes, whereas the patients believed otherwise. Both physicians and patients considered self-monitoring of blood glucose to be an important link of glucose control; unfortunately, most of the patients failed to do so in practice. In addition, physicians considered “improving health insurance coverage for diabetes” as the first important measure and “providing more and easy-to-use diabetes brochures or educational materials for patients” as the second important measure to improve diabetes control. Conclusion: The survey revealed differences between the perspectives of physicians and patients on the potential barriers to optimal diabetes control. The main potential barriers to optimal diabetes control were patient’s poor lifestyle interventions, limited understanding of the danger of diabetes, and poor self-monitoring of blood glucose. From the physicians’ perspective, China’s primary focus about diabetes control in the future should still be put on diabetes education, particular the importance of lifestyle interventions.

Description of the sources of mortality data in China National Mortality Surveillance System Before 2013, the Chinese CRVS included two systems: the vital registration system of the Chinese National Health and Family Planning Commission (NHFPC) (the former Ministry of Health) and the sample-based disease surveillance points (DSP) system of the Chinese Center for Disease Control and Prevention (CDC). The vital registration system was established in 1973 and started to collect data of vital events. By 2012, this system covered around 230 million people in 22 provinces, helping to provide valuable information on both mortality and COD patterns, although the data were not truly representative for the whole China [55]. DSP was established in 1978 to collect data on individual births, deaths and 35 notifiable infectious diseases in surveillance areas [56]. By 2004, there were 161 sites included in the surveillance system, covering 73 million persons in 31 provinces. The sites were selected from different areas based on a multistage cluster sampling method, leading to a very good national representativeness of the DSP [57, 58]. From 2013, the above two systems were merged together to generate a new “National Mortality Surveillance System” (NMSS), which currently covers 605 surveillance points in 31 provinces and 24% of the whole Chinese population. The selection of surveillance points was based on a national multistage cluster sampling method, after stratifying for different socioeconomic status to ensure the representativeness [17, 58].

However, given their less-developed status in particular expressed by under-developed economies, unsound political regimes, low governance capacity, such task seemingly insurmountable. In order to approach the incompatibility between economic development and maintenance of the ecosystem services value, and understand the complex and interlocked nature of the regional institution system of ESAs in developing countries, an ecosystem services value-based adaptive governance model was introduced to identify the deficiencies and failures of existing regional environmental governance and establish innovative arenas and transition agendas for innovating and reframing regional institutions and modifying role of regional actor groups and governance mode in the process of decision making on environmental issues.

    People’s Republic of China Ex-Post Evaluation of Japanese ODA Loan Shaanxi Water Environmental Improvement Project (Shaanxi Province) External Evaluator: Noriyo Aoki, IC Net Limited 0. Summary The objective of the project is to achieve a stable supply of safe water in 13 regional cities in Shaanxi Province by improving water supply facilities, thereby contributing to an improvement in living environment. The project is consistent with priority areas in China’s development policy and in Japan’s ODA policy. Development needs are also high. Therefore, the relevance of the project is high. The main operation and effect indicators, such as population served by water supply, water supply coverage rate and water leakage rate, were achieved mostly as planned, and the beneficiary survey conducted as part of this evaluation study also confirmed a high degree of recognition for an improvement in water supply. Therefore, the effectiveness of the project is high. Although the project needed more time than planned, project costs were mostly as planned, therefore the efficiency of the project is fair. No major problems have been observed in sustaining the institutional and technical aspects of operation and maintenance, and the financial issues regarding some of the water purification plants are headed toward amelioration. Therefore, sustainability of the project effect is high. In light of the above, this project is evaluated to be highly satisfactory. 1.
